It appears that you are immature and may find it difficult either to understand or investigate further in your case.

You have been defrauded for Rs.3 lakhs.   Recovery is the first importance.   Punishment to the culprit is another.

Entrust this case to Police for filing criminal case.

If he agrees to refund the amount  it is well and good, otherwise issue a notice then and there, take personal acknowledgment during his visit and then file Civil case.

You can not do this yourself, and entrust this to advocate as huge sum of Rs.3 lakhs is involved and also save others from the loot by cautioning gullible unemployed..
